The detection reagent used the principle of immunochromatography double antibody sandwich method to make HCG test paper, and can determine the HCG in urine specimen within 3 minutes. During the detection, when the detected urine siphon by colloidal gold labeled monoclonal antibody, formation of antigen antibody colloidal gold complexes, complexes continue to crawl through the package of anti -HCG alpha subunit Mcab was formed when the double antibody sandwich colloidal gold complexes in coating line showing the ribbon, gold colloid antibody excess continue to crawl, and goat anti mouse control line to form colloidal gold immune complexes, showing the ribbon. HCG colloidal gold detection kit is made by double antibody sandwich one step technology. Colloidal gold is used as the indicator mark to detect the HCG concentration in urine to diagnose whether the woman is pregnant. Test paper is a reliable indicator to assist clinical determination of pregnancy.
Human chorionic gonadotropin (HCG) is a glycoprotein hormone produced by the placenta in pregnancy, early pregnancy test by double antibody sandwich one-step technique using colloidal gold indicator, the concentration of HCG was detected in the urine, to confirm whether pregnant women.
